There is a guy talking to me about 12V's but he can't find any and is heading the 24V route instead since they are plentiful and I am not 100% on some things. He is getting it from a 70 year old with low mileage who just replaced the VP44, so I told him that would be the best one. Aside from needing a fuel pressure gauge, better lift pump, use 2 stroke, what else is there? Plus I can't get into enough details about what I just said. He wants to know how long he can run without a gauge and I said however long you want to be second guessing the lift pump. He also wants to know about what to do when the lift pump does go bad. Assuming he has a fuel pressure gauge by then, what exactly do you do? Turn it off instantly and get a new pump? Do they just die or do they peter out over time? If someone could write up a big guide over all of the things I listed plus other things I don't know about, that would be perfect. I have a guide in the 12V section but there isn't one over here so I'm coming up short.
